Radiologic Findings
Chest radiography shows well-defined increased mass opacity in Left apex.
A: Pre-contrast chest CT image shows well-defined 4.8cm sized mass in left apex abutted to the mediastinal pleura.
B: Post-contrast enhanced chest CT image shows well-defined mass with mild contrast enhancement.
The mass shows heterogenous attenuation on pre- and post-contrast CT, composed of low density foci within the mass, suggestive of fatty component. There is no calcification within the mass.
